IS IT POSSIBLE FOR A TIOLET TO CONTINUE TO LEAK FROM THE WAX RING EVEN IF THE TOILET HAS NOT BEEN FLUSHED? I HAVE 3 SMALL SPOTS ON MY LOWER LEVEL CEILING (THE BATHROOM IS DIRECTLY ABOVE) AND I CAN'T FIGURE OUT WHERE THE LEAK IS COMING FROM. I DON'T THINK THE WATER IS COMING FROM AROUND THE SHOWER CURTAIN WHEN SHOWER IS USED.
